Letters Patent No. 96,776, dated November 16, 1869.-

IMPROVEMENT IN COMBINED SCREW AND PIPE-WRENCH.

The Schedule referred to in these Letters Patent and making part of the same.v

To all whom 'it may concern Be it known that I, JV. CLOSE, of Buffalo, in the county of Erie, and State of New York, have invented acertain new and useful Improvement in a Combined Screw andA Pipe-Trench and Pipe-Cutter; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification', in which- Figure 1 is a perspective .view of' a screw-wrench, having combined with it a pawl-drill, which latter is designed to be the subject-matter of a subsequent application.

Figure 2 shows the pawl-drill removed jaws.

Figure 3, side elevation of. the combined screw and pawl-wrench.

Figure 4 shows the pipe-cutter.

Figure 5, the biting-die or plate.

Figure 6, the spring and pin.

Figure 7, the clasp-hook.

Like letters of reference indicate corresponding parts in all the figures.

My invention consists in adapting any ordinary screw or monkej"\vrench to receive various applifrom the ances, whereby it is, in effect, converted into a combined pipe-wren`ch and pipe-cutter, all to be hereinafter fully described.

1n the drawings- A represents the ordinary screw-wrench, having gig.. 1) apawl-drill, B, held firmly in its jaws, thus making ai'emovable working handle for it, which possesses many advantages over the ordinary stationary handle, one'being its double use as-a wrenchand pawl-drill, and its cheapness, thus combined, over theordinary ratchet and pawl-drills; another is, that the pawl is more easily adjusted by beinglisconnected from the handle, as the drill can be set just where wanted in ditlcult positions to get at, and when thus set, the handle can be fastened on in an instant.

I have shown, in red lines, fig. 1, a ditierent way of fastening a pawl-drill outside of the jaws, and there are, in fact, very'many ways in which such a pawl can be attached to the wrench, but I prefer that shown in the drawing, g. 1.

Io hold the pawl perfectly in the wrench, I form on thel square box C, ofthe pawl-drill, flanges a a, which rest just over the sides ofthe jaws b c of the wrench,

thus preventing any up or down movement, and aiding This construction of a pawl-drill, and made without al handle, I believe to be entirely new, and when combined with the wrench, makes a simple and pelfect pawl-drill and wrench.

I form in the side of the movable jaw c of the wrench a hole, la, and a similar hole, i, in stationary jaw b, for the lpurpose ot' holding by a pin, p, and spring, k, a clasp-hook, D, which converts the screw-wrench into an adjustable pipe-wrench.

'Ihis clasp-hook is made forked, and fits Ovcrthe Yjaws c and b of' the wrench. A

In each end of the fork is a hole, which comes op posite to hole h, in movable jaw c of the wrench, and through which the pin 1) of the spring l: passes,suit ably secured on the other side.

The pin of the spring (see tig. 6,) is made square at its junction with the spring, and one eye of the clasphook is made square to receive it and hold the hook v The end of the spring is bent inward, and goes under the screw ofthe movable jaw c, between that and the bar o.

The great advantage of this clasp-hook is, that when arranged on a screw-wrench, as described, it makes an adjustable pipe-wrench which will hold and work on any size pipe, by merely screwing forward or back the thumb-screwl of the wrench. f

To give a greater biting or holding power, I serrate. the face of the stationary jaw b, shown by iigs. 1, 2, 3, 4, Sco.; or, if desired, the hook part of clasp-hook I) can be indented in a similar' manner.

As a substitute for this, I form a recess, j, in -the smooth face of the stationary jaw l), into which a die, E, with a biting surface, is set, like tig. 5.

To make a perfect pipe-cutter, in combination with the wrench and clasp-hook, I form a curved knife or cutter, F, with a projecting back, m, that sets in the recess j of the face-of the wrenchi The pipe to be cut is inserted and held by clasphook D and cutter F, the back m of which sets in the recess j ofthe stationary jaw b.

To insure its being held tightly, and also to follow the crease as the knife cuts the pipe, I make the screw-nut l of Octagon shape, and form a hole, n, in it, in which to insert a lever to turn it, as the thumb and fingers would be insuflicient at times.

If found desirable, a recess may be formed in the jaw of the clasp-hook, for receiving the dies, similar to that in the stationary jaw b, and either may be made like the claws of a hammer, if necessary, and the clasp-hook may be made with a tongue, instead of a fork, and set inthe recess of the stationary jaw, but I prefer the-manner first presented and shown in the drawings.

The clasp-hook may also have the forks combined and set overl the jaws of the wrench, as shown in red lines, fig. 3, and instead of spring k, rubber a spring may be used inv any suitable manner.

I form the hole z' in the stationaryjaw`b, in order to arrange the claw-hook in that jaw, if desired, as shown 2. The angular pin p, and spring k, cast together, in combination with the hook D, and the jaws of a wrench, for the purpose described.

3. The opening j, in the face of the stationary jaw, in connection with the removable serrated block E, or pipe-cutter F, having projection m, for the purpose Set forth.

In witness whereof, I have hereunto signed my name, in the presence of two subscribing witnesses.

J. W. CLOSE.
